Power Saving Switch Connector (JGS1)
Fan Power Connectors: CPU_FAN1, SYSFAN1/2/3/4
The fan power connectors support system cooling fans with +12 V. When
connecting wires to the connectors, always remember that the red wire is
positive and should be connected to the +12 V pin; the black wire is Ground
and should be connected to GND. If the mainboard has a system hardware
monitor chipset onboard, you must use a specially designed fan with a
speed sensor to take advantage of the CPU fan control.
